Definitions

  • the invention relates to a rotary joint prosthesis having a distal component and a proximal component and a coupling piece connecting them articulated, which comprises a flexion bearing about a first axis and a rotary bearing about a second axis oriented transversely to the first axis.
  • knee joint prostheses are due to their high load by the body weight and their complex movement, namely the flexion movement (flexion) as a main movement combined with a rotation of the rail bone relative to the thigh as a secondary movement relatively susceptible to interference from wear or disease.
  • flexion movement flexion
  • rotation of the rail bone relative to the thigh
  • secondary movement relatively susceptible to interference from wear or disease.
  • Another requirement of the joint prosthesis is that it must have sufficient stability, especially if the holding device consisting of soft tissue (ligaments, etc.) is already weakened.
  • a tibial component and a femoral component are interconnected via a coupling piece having an axle eye for receiving an axis carrying a femoral component so as to provide a flexion joint.
  • the coupling piece has a bearing bush facing towards the tibia, in which a pin arranged on the tibial component engages, so as to form a rotary joint.
  • a sliding sleeve made of plastic is arranged in the bearing bush. It is hat-shaped with a hemispherical, the top of the pin covering top. The essentially cylindrical jacket bears against the wall of the coupling piece forming the bearing bush. This results in a Verschungs free. However, it has been shown that it can still lead to pinching of the bearing sleeve. For the patient, this defect of the prosthesis usually means a revision surgery.
  • the invention has for its object to improve a joint prosthesis of the type mentioned in that it is more robust and easier to dismantle in case of revision.
  • a rotary joint prosthesis having a distal component for anchoring in a first bone, a proximal component for anchoring to a second bone, and a coupler that forms a flexion bearing with the proximal component about a first axis and the second component comprises a pin and bushing Rotation bearing transverse to the first axis oriented second axis forms, and in the bearing bush, a sliding sleeve comprising the peg and a completely umhuntnde support sleeve is arranged, which is fastened via a securing element to the coupling piece, wherein the invention provides that the securing element is an actuator within the Support sleeve and has two aligned holes in support sleeve and coupling piece tensile strength with the coupling piece is connected.
  • the core of the invention is the idea to position the actuator for the fuse element in the interior of the bearing bush. Unlike the closest prior art then access to the security element does not need to lead from the outside through the coupling piece, for which a corresponding opening in the coupling piece was required, which has led to its weakening. Thanks to the inventively placed inward actuator, the opening on the coupling piece can be significantly smaller, which is why it gains in stability. Next can thus attack the fuse element directly to the bearing bush, so that it can be safely pulled out even if they are relatively stuck. Thus, the conditions are created to reinforce the support sleeve by thicker material and so even incorporated in the load flow, resulting in a corresponding relief of the sliding sleeve usually made of plastic material. This allows even greater loads to be safely absorbed, and the risk of failures due to overloading decreases. Under thick material thickness of the support sleeve is understood here that the material thickness is at least 0.8 times the material thickness of the sliding sleeve.
  • an access opening to the actuator is provided on the sliding sleeve.
  • the actuator is seen from the entrance side of the pin behind the sliding sleeve, and can take this in the release of the fuse element.
  • the fuse element acts with its actuator at the same time as a puller for sliding sleeve. Even damaged sliding sleeves, in particular due to squeezing or cold flow of the plastic material in case of overload, can thus be easily removed.
  • a particularly useful embodiment of the fuse element is a screw whose head forms the actuator.
  • the width of the access opening is smaller than the width of the head of the screws. It has proven useful if the access opening of the sliding sleeve expands towards the support sleeve. This results in a conicity that favors the impression.
  • bores for the securing element in the support sleeve on the one hand and the coupling piece on the other hand are designed with different widths.
  • Such a stepped bore has the advantage that the securing element can be inserted with its shaft through the support sleeve until it rests with his head.
  • This can be achieved by tightening the securing element, in particular by tightening the screw, a secure positioning, not only the fuse is released by loosening, but also the sliding sleeve can be pushed out.
  • the sliding sleeve is arranged in the region of its pin-side mouth locking lugs, which engage in an undercut on the inner surface of the support sleeve, secured against axial movement out of the support sleeve. Damage caused by dislocation movement is thus counteracted.
  • the support sleeve is provided with a radially projecting bar, which engages in a complementary shaped recess on the coupling piece. This ensures that the support sleeve does not rotate in an undesirable manner during the rotational movement about the pin.
  • the nose and the recess are arranged at the journal end, the positive connection can be achieved by simply inserting the support sleeve in its bearing bush on the coupling piece.
  • the receptacle for the support sleeve is preferably made smooth-walled with a particular cylindrical inner shape on the coupling piece. This is easy to manufacture and results in a uniformly stable storage, even with an axial movement of the pin in the bearing bush.
  • a receiving surface for a front of the coupling piece Impact protection provided, which is extended over a pocket-like recess in the region of aCWauges.
  • the impact protection acts as a stop for the flexion movement, namely for the extended position. Since the coupling piece can strike against the distal component, the impact protection serves to protect it from damage. In order to remain in its intended position when jerky loads occur, a sufficiently secure attachment is required. In a simple way can be achieved by means of the pocket-like recess that the impact protection is prevented from lifting and dropping from its position on the front of the coupling piece.
  • the pocket-like recess has a rectangular cross section and is flush with the receiving surface.
  • the impact protection can be designed as a continuous plate, which is fixed by inserting the pocket-like recess in position.
  • a maximum of two depressions are formed on the front side in the coupling piece, which act as a displacement safeguard especially with a arranged on the back of the impact protector projection.
  • the endoprosthesis of a knee joint consists essentially of two components 1, 2, one of which is designed as a tibial component 1 and the other as a femoral component 2.
  • a stem 20 which is inserted into a femur of a patient, is followed by a femoral bearing half 21, which has two condyle-like skids 22 projecting in the manner of a fork to the tibial component 1.
  • a tibial plateau 12 which is arranged on a tibial bearing half 11, which is attached via a stem 10 to a lower leg bone of the patient.
  • a coupling piece 3 which has a T-piece 30 as a main body with a arranged in its upper region receiving eye 33 for a pivot pin 34 and a bearing bush 32 for a uplifting from the tibial plateau 11 journal 31.
  • the first bearing (flexion bearing) allows a pivoting movement between the components 1 and 2, so realized a flexion movement between the upper and lower leg.
  • This pivoting movement about the axis of the axle pin 34 thus forms the first axis for the movement of the Knieendogelenkprothese.
  • the pin 31 is aligned, which forms a second axis for a rotational movement with which the femoral component 2 rotates relative to the tibial component 1 about the second axis.
  • the pin 31 projects into the bearing bush 32 on the coupling piece 3. Between the two a bearing insert 4 is arranged. This is fastened in the receiving eye 33 via a securing element 5 located at its upper end in the form of a screw 50.
  • the bearing insert 4 is of a substantially cylindrical basic shape and has at its upper end a hemispherical dome.
  • the bearing insert 4 consists of a sliding sleeve 41 and a support sleeve 42.
  • the outer diameter of the bearing sleeve 41 is chosen so large that there is a slight interference fit in the inner wall of the support sleeve 42.
  • the support sleeve 41 has an opening 40 for the pin entry.
  • a fixation element 43 is arranged circumferentially around the circumference, wherein it is preferably continuous, but may also be interrupted several times.
  • the support sleeve 42 has at its mouth-side end on its outer side a radially projecting strip 45, which in a complementarily shaped recess the inside of the bearing bush 32 of the coupling piece 3 engages positively. Thus, the support sleeve 42 is prevented from undesirable rotation relative to the coupling piece 3.
  • the sliding sleeve 41 may be provided on the inside of the sliding sleeve 41 has a conically tapering shape. It facilitates the insertion of the pin 31 in the bearing insert. 4
  • the sliding sleeve 41 has an access opening 46. It is provided with a conical edge surface, whose width increases towards the top.
  • a first bore 47 and in the receiving eye 33 a second bore 38 is provided, which is provided with an internal thread 39.
  • an internal thread 48 is arranged in the bore 47 of the support sleeve 42.
  • the screw 50 is used as a backup and screwed with its shaft 51 in the internal thread 39.
  • the head 52 of the screw 50 has a larger diameter than the width of the access opening 46. It lies firmly on the inside of the support sleeve 42 and secures them in position.
  • the coupling piece 3 is provided with a plane receiving surface 35.
  • a pocket 36 is formed in the receiving eye 33, the plan at its base merges into the receiving surface 35.
  • a holding opening 37 is provided, which is designed as a passage opening in the bearing bush 31 to the support sleeve 42.
  • an impact protection plate 6 Placed on the receiving surface 35 and inserted with its upper edge in the pocket 36 is an impact protection plate 6.
  • a projection 62 is formed on its rear side, which engages positively in the retaining opening 37 and thus secures the impact protection plate 6 in its position.
  • an extractor 7 is provided, which is designed as a screwdriver with a shaft 70 on the handle 71 at its rear end.
  • a guide trough 72 At the front end of a guide trough 72 is arranged, which has a larger diameter than the shaft 70, and whose diameter is matched to the inner width of the bearing insert 4. Under tuned here is understood that it has about 1 mm undersize, so that there is a clearance fit.
  • a screw tip 73 is arranged, which has an external thread 74. It is designed so that it fits into the internal thread 48 in the bore 47.
  • the locking screw 50 in a conventional manner by means of a screwdriver (not shown) solved.
  • the screw 50 presses with its head 52, since it has a greater width than the passage opening 46 in the sliding sleeve 41, the sliding sleeve 41 down from the support sleeve 42 out.
  • the pressing out can be assisted by a compression of the sliding sleeve 41 in the region of the mouth 40, so as to facilitate disengagement of the locking elements 43, 44.
  • the support sleeve 42 can be removed from the bearing bush 32.
  • the extractor 7 can be introduced into the interior of the support sleeve 42 after removal of the locking screw 50, and the extractor 7 with its thread 74 on the Screw tip 73 are screwed into the internal thread 48 of the support sleeve 42.
  • the extractor 7 is tensile strength connected to the support sleeve 42 and it can be pulled out of the bearing bush 32.
  • the invention allows a relatively small access hole in the form of the bore 38 in the coupling piece.
  • the coupling piece can be solid, ie in particular in the region of the receiving eye 33 No further breakthroughs are required.
  • the invention allows a secure attachment of the bearing insert 4 and a simple removal.
  • the arrangement of the impact protection plate 6 in the pocket 36 also avoids weakening, as has occurred in the prior art by a large number of adhesive holes in the area of the receiving surface 35.
